MAGAZINE FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 313,851, dated March 17, 1885.

Application filed November 15, 1884. (Medal) To all whom it muylconcern:

Be it known that I. RosWELL F. CooK, of llion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements inMagazines-for Fire- Arms, of which the following is aspecificatiom This invention relates to that class of car tridge magazines or boxes designed to be used with the gun patented to J. Lee, November been devised for use in these boxes, some of zigzag form, others coiled, and still others curved, with a rigid arm attached; but in all cases they have been made of flat strips or,

pieces of steel. Many objections have been found to exist'to these flat springs, it being somewhat difficult to secure a perfectly-uniform temper, and they beingtoo expensive. Moreoventhey do not possess the degree of elasticity that is desired for this purpose, and are liable to become setor to break when kept compressed for a long time, as they must be when the boxes are filled with cartridges, thus destroying the efficiency of the magazine.

The object of my present in vention is to pro-' vide these magazine-boxes with aspring which -Will obviate all these difficulties or objections,

which can be compressed into a small space, and shall be cheap to manufacture.

as represented in the drawings, preferably using-steel wire for the purpose, though that is not absolutely necessary. To construct this spring, I take a piece of wire of the proper To ac-' compl'ish this, l". make the spring Bot. wire,

spring shown is composed of four folds or coils, the ends ofeach of the outer folds or coils being bentbackward and extended back far enough to afford a' fiat bearing at both terminals or ends, so as to prevent any tendency 5 0f the spring to tip sidewise when compressed,

a: shown at a, Fig. 2. As shown in Fig. 2,

these bearing ends are both at the front, so

- that when placed in the box and the follower 2 with the cartridges 0 are placed thereon the spring will naturally exert its pressure priniarily 'on the front part of the follower, thus keeping the front end-orpoi'ntof the cartridges elevated, as is necessary to enable them to be shoved fromthe top of the box directly into .65

the chamber of the gun.

By. examining Fig. 1, it will be seen that the coils of the spring are so arranged-that the front end, a,- of each projects slightly in advanceof the one next below it, so that when compressed the several folds will overlap each other, thus causing them to move parallel with the front of the box. This is effected by giv-' ing-a different inclination to the alternate bars of the various folds orooils, as shown in Fig. 7 5 1, in which it Will be seen that the bar 0 of each fold is more inclined than the. bar at of the same fold or-coil, as shown more clearly in Fig. 1. If the coils or folds be made of uni-' form length, their rear ends will also overlap 8o in the same manner, and I so preferto make them, as I find the spring thus made to operate perfectly, Still it is obvious that if desired the coils or folds, especially the intermediate ones, may be made of a ditferent length from the others; but if madeshorter it will decreas'eto that extent the elasticity of the spring,

which is not desirable.-

as possible, and yet secure a sufficient extent of spring to possess the required degree of force and elasticity and bear the requisite com-' pression without dangerof breaking or being set.

It will be seen that each of thebars 0 and m which compose the spring act as springs, and that thus the spring is extended over a much greater extent orlcngth of spring than is the ease with any of the va'rious'forms of flat springs heretofore used in these boxes, and that, consequently, there is much less danger of breakingor injuring the spring when E0111: pressing it, and there is a correspondingly greater degree of elasticity to the spring. By slightly bending the two outer bars, as shown in Fig. 2, opposite the points where the bent ends n terminate, the spring will bear only for a short distance on the outer bars, thereby leaving the balance of those bars also to exert their spring force.

The advantages of this spring for the purpose are obvious, and its simplicityand cheapness of construction, as well asits greater cfficiency and durability, render it especially valuable in this connection, more particularly as when these boxes are used for military purposes they'are expected to be thrown away,

Having described my invention, what I claim is 1. In combination with a cartridge-box,substantially such as shown, the wire spring B, composed of a series of coils or folds made to conform to the shape of the box transversely, substantially as shown and described.

2. A spring for magazine-boxes, composed of a piece of spring-wire coiled or folded to correspond to the interior of the box, and having its terminal or bearing ends arranged at the front, whereby its pressure is brought to bear upon the front portion of the follower, and thus keep the front end of the cartridges elevated,substantially as shown and described.

. 3. In combination with a cartridge-box,sub-.

stantially such as shown, the spring B, composed ot spring-wire bent or folded into a series of coils or folds, with the front end of each coil or fold overlapping or projecting beyond the one next below it, whereby the ends of said coils or folds are caused to move in a line parallel with the front or inclined end of the box, substantially as shown and described.
